Midroll Spacing

Find podcast midroll placements that violate a supplied spacing minimum.

Description

Midroll spacing checks the intervals between successive ad placements.

Midroll spacing checks the intervals between successive ad placements. A minimum gap applies to each adjacent pair.^[1]

Find podcast midroll placements that violate a supplied spacing minimum.

When to use Midroll Spacing

Use this tool to find podcast midroll placements that violate a supplied spacing minimum.

Prepare the text, recorded observations, aligned figures or editorial criteria requested. Confirm what each label, count, timestamp or supplied flag represents before interpreting the result.

How to use Midroll Spacing and understand its results

Prepare the text, recorded observations, aligned figures or editorial criteria requested. Confirm what each label, count, timestamp or supplied flag represents before interpreting the result.
Enter midrollTimesSeconds, minimumSpacingSeconds using the field table and calculation rules, then run the tool.
Read minimumObservedSpacingSeconds, violatingPositions, violationCount. The explanation below defines the units, signs, ordering and any flags or placeholder values.
If the tool reports an input issue, correct the values and run it again. Apply the stated assumptions when interpreting a successfully returned result.

Input field	Meaning	Value type; see rules below	Requirement
midrollTimesSeconds	Midroll timestamps (s)	list of number	Required
minimumSpacingSeconds	Minimum spacing (s)	number; minimum: 0	Required

Enter at least two nonnegative strictly increasing timestamps and nonnegative minimum seconds. Return smallest gap, violation count and one-based positions of later placements in violating pairs. Equality passes.

gap_i=time_i−time_(i−1); violation if gap<minimum

Units, indexing, boundary conditions and exceptional cases are defined in the calculation rules above.

Output field	Meaning	Value type
minimumObservedSpacingSeconds	Minimum observed spacing (s)	number; minimum: 0
violatingPositions	One-based positions after short gaps	list of number
violationCount	Spacing violations	integer; minimum: 0

Limitations and assumptions

No placement is moved and no audio content, suitability or monetization policy is analyzed.

Numeric inputs must be finite. Follow the calculation-specific rules for overflow, underflow and exceptional cases. Lists are limited to 100,000 entries; the rules above may require smaller limits. Missing required fields, extra fields, wrong value types and violations of the calculation rules are input errors.
